One thing to point out... is that with the addition of closer lobe centerlines (more overlap), the worse the idle, the lower the vacuum signal, and typically, when you move the lobes closer together (more overlap, you move the torque peak upward (peak power coming in at a higher rpm), and typically, lower and midrange power suffer.

It's always a trade-off with cams. When in doubt, choose the smaller...

The 34mm ports can quite easily support 235Bhp. And, I'm quite sure that I can get the same combo upto at least 250Bhp... all with the peak Hp coming in at 6000rpms (which is very good for a true daily driven street car).
